Yup, I confirm the same bug in windows 8, also there's no ICC-Profiles workaround that I've found, so far. I did work out an easier solution, though, I downloaded Picasa and set that as the default image viewer. It's incredibly zippy! (It's amazing how ridiculously bad windows 8 is at a lot of simple things, I've bought a relative a new one and am setting it up at the moment and the number of tweaks that I have to do in order to make it usable is totally ridiculous :))

Hello, I also use Windows 8 and I have the same bug problem and I simply downloaded this new free picture viewer http://www.coolutils.com/PhotoViewer since I'm too busy (or lazy) to do all those tweaks :))
